Question

a car drives 100.0 m from point A (in 10.78 seconds) toget to point B. then drives back to the starting point in 90.1seconds. what is the average speed for the total distance (200.0m)? what is the magnitude of the average velocity for the totaldistance? a car drives 100.0 m from point A (in 10.78 seconds) toget to point B. then drives back to the starting point in 90.1seconds. what is the average speed for the total distance (200.0m)? what is the magnitude of the average velocity for the totaldistance?

Explanation / Answer

speed does not take into account direction d= vt 200= v(10.78+90.1) v= 1.98 m/s velocity must take into account direction, and so, since thecar ends up at point A, its starting point, the total distance ormore specifically the displacement is 0 0= vt v=0 m/s
